Raycast available for VisionOS?

Raycasting is supported on visionOS, here is a full example to demonstrate that:

import SwiftUI
import RealityKit

struct ImmersiveView: View {
    
    let entity = ModelEntity(mesh: .generateSphere(radius: 0.1))
    
    var body: some View {
        RealityView { content in
                        
            entity.generateCollisionShapes(recursive: false)
            entity.components.set(InputTargetComponent())
            entity.position = [0, 1, -1]
            
            content.add(entity)
        }
        .gesture(tapGesture)
    }
    
    private var tapGesture: some Gesture {
        
        TapGesture()
            .targetedToAnyEntity()
            .onEnded { value in
                
                let scene = value.entity.scene!
                
                let hits = scene.raycast(from: [0, 1, 0], to: [0, 1, -2])
                
                guard !hits.isEmpty else {
                    print("No hits.")
                    return
                }
                
                for hit in hits {
                    print("Hit distance:", hit.distance)
                }
            }
    }
}

I have a visionOS app that shows an immersive space. All my ModelEntities are programmatically created. I tried your code, but my entities have as property scene always nil, so I cannot use your code. How is the scene property set?
